Chapter 1 Product Overview Fan Modules

Procedures for replacing and installing the power supplies are available in the Removing and Installing AC Power Supplies section.

Fan ModulesThe Cisco MDS 9148S switch supports two hot-swappable fan modules that allow the switches to continue to run if a fan module is removed, provided that the preset temperature thresholds have not been exceeded. You can swap out a fan module without having to bring the system down. Each fan module on the Cisco MDS 9148S switch has two fans.

Caution The Cisco MDS 9148S switch has internal temperature sensors that can shut down the system if the temperature at different points within the chassis exceed certain safety thresholds. To be effective, the temperature sensors require the presence of airflow; therefore, in the event a fan module is removed from the chassis, the Cisco MDS 9148S switch will shut down after five minutes to prevent potentially undetectable overheating. However, the switches will shut down sooner if the higher-level temperature threshold is exceeded. For normal operation, the Cisco MDS 9148S Switch requires four fans. Fan module status is also indicated on a front panel LED.

Procedures for replacing and installing the fan modules are available in the Removing and Installing Fan Modules section.

Cisco MDS 9148S Multilayer Switch PortsThe Cisco MDS 9148S switch provides host, target, and Inter-Switch Link (ISL) connectivity. It provides up to 48 autosensing and autonegotiating Fibre Channel ports capable of speeds of 2-, 4-, 8-, and 16-Gbps. The first 12 ports are licensed by default. On-Demand Port Activation Licensing allows expansion up to 48 ports, with additional ports available as an 12-port group.

Switch LEDsThe front panel of the Cisco MDS 9148S switch includes the LEDs shown in Figure 1-3. You can use the LEDs on this panel to quickly identify system status.

Note Cisco MDS 9148S switch LEDs do not indicate the port speed.

Installation Guidelines

Follow these guidelines when installing the Cisco MDS 9148S Switch:

• Plan your site configuration and prepare the site before installing the switch. The recommended site planning tasks are listed in Appendix 1, “Site Planning and Maintenance Records.”


OL-20185-01


• Ensure there is adequate space around the switch to allow for servicing the switch and for adequate airflow (airflow requirements are listed in Appendix 1, “Technical Specifications”).

• Ensure the air-conditioning meets the heat dissipation requirements listed in Appendix 1, “Technical Specifications.”

• Ensure the cabinet or rack meets the requirements listed in Appendix 1, “Cabinet and Rack Installation.”

Note If the front cabinet mounting rails are not offset from the front door or bezel panel by a minimum of 3 inch (7.6 cm), and a minimum of 5 inch. (12.7 cm) if cable management brackets are installed on the front of the chassis, the chassis should be mounted rear-facing to ensure the minimum bend radius for fiber-optic cables. See the “Installing the Switch in a Cabinet with Insufficient Front Clearance” section on page 2-21.

Note Jumper power cords are available for use in a cabinet. For more information, see the “Jumper Power Cord” section on page 1-6.

• Ensure the chassis is adequately grounded. If the switch is not mounted in a grounded rack, we recommend connecting both the system ground on the chassis and the power supply ground to an earth ground.

• Ensure the site power meets the power requirements listed in Appendix 1, “Technical Specifications.” If available, you can use an uninterrupted power supply (UPS) to protect against power failures.

Caution Avoid UPS types that use ferro-resonant technology. These UPS types can become unstable with systems such as the Cisco MDS 9000 Family, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.

• Ensure that circuits are sized according to local and national codes.

For North America, the 300-W power supplies require a 20-A circuit. If you are using a 200- or 240-VAC power source in North America, the circuit must be protected by a two-pole circuit breaker.

Caution To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the switch are within current ratings for wiring and breakers.

• As you install and configure the switch, record the information listed in the “Site Planning and Maintenance Records” section on page 1-1.

• Use the following screw torques when installing the switch:

– Captive screws: 4 in-lb

– M3 screws: 4 in-lb

– M4 screws: 12 in-lb

– 10-32 screws: 20 in-lb

– 12-24 screws: 30 in-lb


OL-20185-01


Required Equipment

Gather the following tools before beginning the installation:

• Number 1 Phillips screwdriver with torque capability

• 3/16-in. flat-blade screwdriver

• Tape measure and level

• ESD wrist strap or other grounding device

• Antistatic mat or antistatic foam

The following additional items (not found in the accessory kit) are required to ground the chassis:

• Grounding cable (6 AWG recommended), sized according to local and national installation requirements; the required length depends on the proximity of the switch to proper grounding facilities

• Crimping tool large enough to accommodate girth of lug

• Wire-stripping tool

Unpacking and Inspecting the Switch

Caution When handling switch components, wear an ESD strap and handle modules by the carrier edges only. An ESD socket is provided on the chassis. For the ESD socket to be effective, the chassis must be grounded through the power cable, the chassis ground, or the metal-to-metal contact with a grounded rack.

Tip Keep the shipping container in case the chassis requires shipping in the future.

Removing and Installing Fan Modules

This section provides instructions for removing and installing the fan modules for the Cisco MDS 9148S switch.

Removing a Fan Module on the Cisco MDS 9148S Switch

The fan module is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damaging the system.

Caution The Cisco MDS 9000 Family has internal temperature sensors that can shut down the system if the temperature at different points within the chassis exceed certain safety thresholds. To be effective, the temperature sensors require the presence of airflow; therefore, in the event a fan module is removed from the chassis, the Cisco MDS 9000 Family will be shut down after five minutes to prevent potentially undetectable overheating. However, the switches will shut down sooner if the higher-level temperature threshold is exceeded.

Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258

To remove the existing fan module, follow these steps:

Step 1 Locate the fan module in the back of the switch.

Step 2 Slide the seating tabs toward the center of the fan module.

Step 3 Grasp the fan module handle and pull it outward.

Connecting the 10/100/1000 Ethernet Management PortThe autosensing 10/100/1000 Ethernet management port is located on the left side of the front panel (labeled 10/100 MGMT), to the right of the Console port. This port is used for out-of-band management of the Cisco MDS 9148S switch.

Use a modular, RJ-45, straight-through UTP cable to connect the 10/100/1000 management Ethernet port to external hubs and switches. To connect to a router, use a crossover cable.

Connecting to a Fibre Channel PortThe Fibre Channel ports are compatible with LC-type fiber-optic SFP transceivers and cables (see “Removing and Installing Cables into SFP Transceivers” section on page 1-40). You can use these ports to connect to the SAN or for in-band management. For information about configuring the switch for in-band management, see the Cisco Fabric Manager Fundamentals Configuration Guide and the Cisco NX-OS Fundamentals Configuration Guide.

The Cisco MDS 9148S switch supports both Fibre Channel and Gigabit Ethernet protocols for SFP transceivers. Each transceiver must match the transceiver on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications. SFP transceivers can be ordered separately or with the Cisco MDS 9148S switch.

Warning Class 1 laser product. Statement 1008

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Caution Wear an ESD wrist strap connected to the chassis when handling transceivers. Keep optical connectors covered when not in use, and do not touch connector ends. The fiber-optic connectors must be free of dust, oil, and other contaminants.

Chapter 1 Connecting the Cisco MDS 9148S Switch Connecting to a Fibre Channel Port

Note Use only Cisco SFP transceivers on the Cisco MDS 9148S switch. Each Cisco SFP transceiver is encoded with model information that enables the switch to verify that the SFP transceiver meets the requirements for the switch.

The Cisco MDS 9148S switch supports SFP transceivers with the following two types of latching devices:

• Mylar tab latch (Figure 1-2)

• Bale-clasp latch (Figure 1-3)

Figure 1-2 SFP Transceiver with Mylar Tab Latch

Figure 1-3 SFP Transceiver with Bale-Clasp Latch

Installing an SFP Transceiver

To install an SFP transceiver, follow these steps:

Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.

Caution If the transceiver does not install easily, ensure it is correctly oriented and the tab or clasp are in the correct position before continuing.

Step 2 Remove the dust cover from the port cage.

Step 3 Remove the dust cover from the port end of the transceiver.

Step 4 Insert the transceiver into the port:

• If the transceiver has a mylar tab latch, orient the transceiver with the tab on the bottom, and then gently insert the transceiver into the port until it clicks into place.

• If the transceiver has a bale-clasp latch, orient the transceiver with the bale clasp on the bottom, close the bale clasp by pushing it up and over the transceiver, and then gently insert the transceiver into the port until it clicks into place.

Step 5 Insert or leave the dust plug in the cable end of the transceiver if a cable is not being installed in the transceiver.

Removing an SFP Transceiver

To remove an SFP transceiver, follow these steps:


Step 2 Perform these steps if cable is installed in the transceiver:

a. Record the cable and port connections for later reference.

b. Press the release latch on the cable, grasp the connector near the connection point, and gently pull the connector from the transceiver.

c. Insert a dust plug into the connector on the cable.

d. Insert a dust plug into the cable end of the transceiver.

Tip If the transceiver does not remove easily in the next step, push the transceiver all the way back in and then ensure that the latch is in the correct position before continuing.

Step 3 Remove the transceiver from the port:

• If the transceiver has a mylar tab latch, gently pull the tab straight out (do not twist), and then pull the transceiver out of the port.

• If the transceiver has a bale-clasp latch, open the clasp by pressing it downwards, and then pull the transceiver out of the port.

Step 4 Insert a dust cover into the port end of the transceiver and place the transceiver on an antistatic mat or into a static shielding bag if you plan to return it to the factory.

Step 5 Protect the optical cage by inserting a clean cover if another transceiver is not being installed.

Removing and Installing Cables into SFP Transceivers

Caution To prevent damage to the fiber-optic cables, do not place more tension on them than the rated limit and do not bend to a radius of less than one inch if there is no tension in the cable, or two inches if there is tension in the cable.

Installing a Cable into an SFP Transceiver

Caution To prevent possible damage to the cable or transceiver, install the transceiver in the port before installing the cable in the transceiver.


OL-20185-01


To install a cable into a transceiver, follow these steps:


Step 2 Remove the dust cover from the connector on the cable.

Step 3 Remove the dust cover from the cable end of the transceiver.

Step 4 Align the cable connector with the transceiver and insert the connector into the transceiver until it clicks into place. (See Figure 1-4).

Figure 1-4 Connecting the LC-Type Cable to a Fibre Channel Port

Caution If the cable does not install easily, ensure it is correctly oriented before continuing.

For instructions on verifying connectivity, see the Cisco Fabric Manager Fundamentals Configuration Guide and the Cisco NX-OS Fundamentals Configuration Guide.

Removing a Cable from an SFP Transceiver

Caution When pulling a cable from a transceiver, grip the body of the connector. Do not pull on the jacket sleeve, because this can compromise the fiber-optic termination in the connector.

Caution If the cable does not remove easily, ensure that any latch present on the cable has been released before continuing.

To remove the cable, follow these steps:


Step 2 Press the release latch on the cable, grasp the connector near the connection point, and gently pull the connector from the transceiver.

Step 4 Insert a dust plug onto the end of the cable.

Maintaining SFP Transceivers and Fiber-Optic Cables

SFP transceivers and fiber-optic cables must be kept clean and dust-free to maintain high signal accuracy and prevent damage to the connectors. Attenuation (loss of light) is increased by contamination, and it should be kept below 0.35 dB.

Follow these maintenance guidelines:

• SFP transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventive wrist strap that is connected to the chassis.

• Do not remove and insert a transceiver more often than necessary. Repeated removals and insertions can shorten its useful life.

• Keep all optical connections covered when not in use. If they become dusty, clean before using to prevent dust from scratching the fiber-optic cable ends.

• Do not touch ends of connectors. This prevents fingerprints and other contamination of the connectors.

• Clean regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site’s fibre-optic connection cleaning procedures.

• Inspect routinely for dust and damage. If damage is suspected, clean and then inspect fiber ends under a microscope to determine if damage has occurred.
